> The compare script has several issues after the module system was
> introduced. I need it to be updated to a clean baseline again. Things
> fixed in this patch:
> * Fixed broken conditional for jar/zip comparison
> * Stop comparing jmods for now, should be redundant enough
> * module-info.class needs to be compared using jdk9 javap output
> * SystemModules.class has a lot of non deterministic ordering of Set
> members, making it almost always differ. Ideally this should be fixed
> so that the generator is deterministic, but in the meantime, use some
> creative sorting to work around it.
> * Updated native binary comparisons with the latest from the
> build-infra/hotspot work, both for speeding up compares and being more
> With these changes I now have a clean baseline for a full JPRT
> "buildinfra" build job of two builds with no changes between them.

Looks good to me.
